HAND-STAMP.

$PBCIFICATION forming part of Letters Patent No. 353,161, dated November23, 1886.

Application filed March 29, 1886. Serial No. 196.970. (No model.)

To aZZ whom it may concern:

Be it known that I, Ennnnznn H. Rosn'ns, .Tr., a citizen of the UnitedStates, residing at Brooklyn, in the county of Kings and State of NewYork, have invented certain new and useful Improvements in Hand-Stamps;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters and figures oireference marked thereon, which form a part of this specification.

This invention relates to handstamps for imprinting dates and otherinformation upon suitable surfaces, and its object is to automaticallyadjust certain of the changeable parts of the stamp for each successiveimprint. I accomplish this by putting my printing-types on wheels, andrevolving the latter by means of ratchets, pawls and levers connectedwith an ordinary clock-movement.

In the accompanying drawings, whereinlike letters represent like parts,Figure 1 is a front elevation of the stamp; Fig. 2, a rear elevationthereof; Fig. 3, a topplan thereof; Fig. 4, a cross-section through thetype-wheels and accessories; Fig. 5, an enlarged view of the cam shownin the first figure; Fig. 6, an en larged view of the cam A A, shown inplan in the third figure; Fig. 7, a detached perspectiveof certain partsshown in the second figure; Fig. 8, also a view of parts shown in thesecond figure; Fig. 9, a modified view of the same parts with additions;Fig. 10, a detached view of one of the pawls used in connection with thesystem of ratchets, and shown in the first and second figures; and Fig.11 is a detailed view of a pawl and accessories shown in Fig. 4-.

A is a platform, upon which is a frame, B, and in the top of this frameis a platen, 0, provided with an annular step, 0, wherein are recesses0, for the insertion of blocks 0*, which have on their faces raisedtypesindicating the name of a month or year. These blocks are insertedand removed by hand, as occasion may require. An inking-ribbon passesover the platen, and is carried and adjusted in the customary manner, sothat no description of ribbon or carrier is needed.

In the frame 13 is a shaft, D, to which is keyed a ratchet, E, meshingwith a pawl, F, having apivoted toe, f, and a flat spring, f, to keepthe toe vertical when not under pressure. A rod, G, is pivoted at oneend to the pawl F and at its other end to the pawl H, which is governedby a fiat spring, h, in the manner shown in Fig. 1. This pawl bearsagainst a double cam, I, sleeved upon an extra shaft, i, formed on theclock-fraine, and is operated from the main shaft of the said clockworkby any suitable system of gear-wheels, as indicated in Fig. 1.

In the regular operation of the clockniovements the cam I revolvestoward the left hand, whereby the pawl F is pushed from the right to theleft side of that tooth of the ratchet E which is next to be operatedupon. \Vhen the toe of the pawl H drops into an outer notch of the camI, the pawl F goes into position to turn the ratchet E one space to theleft, and when the toe of the pawl H falls into the inner and largernotch of the cainthe turn is made. A pawl, e, governed by aspring,c,serves to steady the wheel at each turn; but novelty is not claimedfor this device.

Keyed to the shaft D at the opposite extremity from the wheel or ratchetE is another ratchet, K, cooperating with a gravity-pawl, L, which isgoverned bya spring, I, andastud, Z, in the manner shown. This pawl iskeyed to a sub-shaft, lfljournaled in the frame B, and at the inner endof this sub-shaft is keyed a block, M, bearingon its upper face thelegends A. M. and P. M., as indicatedin Fig. 3. \Vhen the legend A. M.is on the printingline in relation to the platen O, the ratchet K andpawl L are in the position shown in Fig. 9; but at the next turn of theratchets E'and K the position is changed to thatshown in Fig. 8, and thelegend 1?. M. then comes to the printing-surface Incasing the shaft D isasleeve, N, to which is keyed atype-wheel, O, bearing figures denotingthe twelve hours of a meridian, and keyed to the same sleeve isaratchet, I, meshing with a pawl, Q, constructed (like the pawl F) withpivot-toe q and spring q, and having an extra spring. q", fitting withinthanotches of the ratchet I, to steady it in making aturn. This pawl ispivoted to a rod, It, and this to a pawl, S, governed by aspring, s, allas hereinbefore stated with referece to the rod G and pawl H, and thepawl S bears againsta cam, T,whieh is keyed to the main shaft of theclock-work, so as to make a completerevolution in company with theminute-hand of the clock.

It is unnecessary further to describe the operation of the mechanism ofthe hour-wheel, because of its similarity to the operation of themechanism pertaining to the meridianal block M.

Sleeved upon the sleeve N is a wheel, U, bearing figures indicating thethirty-one days of a full calendar month. Keyed to the sleeve of thiswheel is a ratchet, V, having thirtyone teeth and meshing with a pawl,XV, having pivot-toe w and spring 20, and this pawl is pivoted to a rod,Y, which connects with a pawl, Z, Fig. 3, which is in all respectslikethe pawl H, and this pawl operates upon a cam, A A, which isoutlined in Fig. 6. This cam is upon the same sleeve as the cam I, andturns with it,so that the position of the wheel U is changed at the endof each twenty-four hours. Whenever a calendar month has less thanthirty-one days, the surplus figures may be skipped by turning theminute-hand of the clock. The wheel V is steadied in turning by a pawl,12, governed by a spring, 1;, as to which novelty is not claimed.

Sleeved upon the sleeve N is a wheel, 13 B, bearing upon its peripherythe figures denoting the successive minutes in an hour, and

keyed to the sleeve of this wheel is a ratchet, O 0, containing sixtyteeth and meshing with a pawl, D D, having toe cl (Z and spring 03 d,which pawl is connected to a rod, E E, a pawl, F F, and a ratchet, G G,having sixty teeth, and which is upon the same sleeve as the cam T, sothat by this arrangement, and in a manner already sufficientlydescribed, the position of the wheel B B is changed every minute.

Having thus sufficiently described my invention, what I claim to be newand useful, and desire to secure by Letters Patent, is the following:

1. In a hand-stamp, a platen, as 0, provided with an annular step, c,recesses c, and movable blocks 0 for the purpose of imprinting lettersor other characters upon any suitable surface.

2. The combination, in ahaudstamp, of any suitable supports with thetype-wheel U, the ratchet V, the pawl W, having toe w and spring 20, therod Y, the pawl Z, having spring z, the cam A A, and an ordinaryclock-movement to revolve said cam, whereby the characters representingthe current day of a month may be automatically adjusted.

3. The combination, in a handstamp, of any suitable supports with theblock M, the ratchets E and K, the pawl F, having toe f, and springf,the rod G, the pawl H, having spring h, the cam I, the pawl L, and anordinary clock-movement to revolve said cam, whereby the charactersrepresenting the meridianal divisions of a day may be automatic allyadjusted.

4. The combination, in a hand-stamp, of any suitable supports with thewheel 0, the sleeve N, the ratchet P, the pawl Q, having toe q, andspring q, the rod It, the pawl S, having spring 8, the cam T, and anordinary clock-movement to revolve said cam, whereby the charactersrepresenting the hours of a meridianal division of a day may beautomatically adjusted.

5. The combination, in a hand-stamp, of any suitable supports with thewheel B B, the

ratchet O O, the pawl D D, having toe d d, and spring cl (2, the rod EE, the pawl F F, having spring ff, the ratchet G G, and an ordinaryclock-movement to revolve said ratchet last named, whereby thecharacters representing the minutes of an hour may be automaticallyadjusted.

In testimony whereof I flffiX my signatu rein presence of two witnesses.
